A diving expedition off Easter Island, 60–150 meters beneath the surface (the “twilight zone”), reveal new species of fish and invertebrates. In collaboration with SUBELAB Pontificia Universidad Católica de Chile, a scientific team from the California Academy of Sciences became the first divers to study mesophotic ecosystems off Rapa Nui. An orange colored sea biscuit, and four fish collected are almost certainly new species. California Academy of Sciences Ichthyology Curator Luis Rocha plans to give the fish all Rapa Nui names in honor of the local culture.
